problem #7

5500 8-cyl Diesel

  • 30,000 miles


The ignition switch is faulty! the switch must be moved around in the switch to start the truck. Additionally while driving the truck may just quite running, this causes the power steering and brakes to become manual. This becomes very dangerous when hauling loads as stopping distances are greatly increased, not to mention nearly impossible to steer. If you are going around a corner when this happens you may not make the corner resulting in a collision with oncoming vehicles. This ignition switch failure is common in this year of Ram truck it doesn't seem to matter if your driving or setting at a light the truck quits running and may not be able to restart without replacing or repairing the switch. So far Fiat Chrysler has not done anything to fix the design, it appears they are happy collecting the $300 + dollars to replace the switch just to have them go out again in less than a year. Just look at the internet, many issues. This is defiantly a safty hazard and should be a recall item.

When driving the magnetic key ignition module was shorting out. This caused the truck to loose the majority of drivers control at 65 mph on the highway, then the key would make contact and restart the motor causing convulsions in running. This operating condition almost caused a semi truck to rear end my truck. Four days after replacing the $800 ignition system, we also had to replace the flex plate & starter due to the centrifugal force from the motor restarting under highway speeds it destroyed the flex plate backed the flex plate bolts out and deformed the bolt holes in the back of the crank.

On October 1 2015 at 6:45 in the morning our Ram 5500 was backed into the driveway and turned off. Shortly thereafter the driver noticed smoke and opened the hood. There was a fire. He used the fire extinguisher to put it out and disconnected the battery cables. We had the truck towed. I contacted Dodge and wasn't informed that I would hear from an investigator from Dodge that was going to look at the truck. I was told they wanted to investigate why the fire happened. After multiple phone calls over the next few days placed to Dodge I was getting no answers. I asked to speak to a supervisor and was told I would hear back in 24 to 48 hours. I did not hear back at all in the following days. I then got the truck fixed at my own expense. I operate a small business and had to have this truck running. The auto shop replaced the alternator as that was burnt and appeared to be the problem. I've still yet to hear from Dodge on their response. This truck only has 28,000 miles. On an additional note it qualified for the federally mandated buy back, they have not been responsive to phone calls concerning that as well.

On the evening of July 30, 2015 while driving my 2012 Dodge Ram 5500 utility truck, there was a fire in the engine compartment which I believe was due to recall P65. This recall is for the diesel fuel heater electrical connector. This vehicle was taken to dealerships multiple times for repair, yet I was told that no part was available to perform recall. This truck was deemed a total loss.

On March 2, 2014 while sitting in our 2012 Dodge 5500 4 X 4 the low fuel light came on and we opened hood and tipm was smoking again. We just got the truck back from the dealer from the first tipm fire 4 days before. I jumped out of the truck and disconnected the batteries and fled from harms way.
